I spend a great deal of time shaking field marking aerosol paint
cans
for my daughter's soccer team. I don't want to pay for an
expensive
paint shaker, but I find shaking cans for 1-3 minutes after the ball
rattles a major pain in the shoulder. At twelve cans, that's about
a
half an hour
of standing around shaking cans.

If I had a seven or eight-foot flexible pole with a clamp to hold
the
can perpendicular to the stick, and a pivoted plate on the other, I
could stand on the plate and shake the pole back and forth. The
flexible pole would give it a good whip on each stroke. This setup
would be more ergonomic than shaking the can by hand (back and
forth as opposed to side to side), because I would be able to get
my
legs and back into the action

Once I had shaken all of the cans, it would be nice if the cans
could
clamp to the outsides of the wheels of the spray cart. This would
give them a couple of hundred turns apiece to keep them mixed,
and
I could switch them out with other cans as they are used.

Load all your cans into a sturdy box with a locking lid. Secure this box (with all cans oriented upwards) to the hub of your automobile wheel with tensioned web straps. Drive to the soccer field. All the cans will be well shaken. (Helpful Tip: To avoid premature paint application, take care not to parallel park too close to the curb when arriving at your destination if the box is strapped to a passenger-side wheel.)

I'm guessing normzone's comment was in response to jurist's whose comment was in response to your post. Your solution is good but, maybe a shorter pole could be used that you could flex while sitting in a chair.

[metarinka] Back story: My local hardware store always
cards me when I buy paint, its apparently a law, and
they're required to keep a record. (It's aerosol and you
can huff the fumes). I always kid the guy who owns the
place that that's my my hair is white.

I finally bought one of these holders for a recip saw at
the end of last season. It worked like a charm until the
plastic strap broke. the strap had teeth and a ratchet
that made it tighten up on the can. I drilled a hole
through the strap and the holder and put a little carriage
bolt through it to hold the strap back on.

This worked as well, until the bolt wore a hole through
the can I was shaking. At eye level. Which then sprayed
me in the face.

I was on my knees washing paint off my face when the
owner of the hardware store arrived to mow the fields.
He put together what happened, but he's given me
endless shit about it.
